However, is it true that the dangers of sleeping with a fan are in accordance with public opinion, or is this just a myth?

Facts on Using the Fan

Allergies and asthma

Hyperthermia is a condition in which the body temperature is very high, above 40°C. In this condition, the mechanisms in the body fail to cool the body temperature.

When in a warm or slightly hot environment, the body will respond by sweating, so that the body temperature remains normal.

But if the air temperature is very hot, the body's mechanisms are no longer able to compensate. As a result, body temperature will rise and hyperthermia occurs.

If you don't get help right away, hyperthermia can lead to dehydration and even death.

Some say that fans can trigger hyperthermia. But in fact, sleeping with the fan on does not cause hyperthermia.

Turning on the fan is actually the easiest and cheapest way to cool the body when the weather is very hot.


Hypothermia is a condition when the body temperature is less than 35°C. This is because the body loses heat quickly, but is slow to produce heat.

If not treated immediately, hypothermia which is generally caused by weather or cold air can cause organ failure and even death.

In Indonesia, which has a tropical and warm climate, the risk of a person getting hypothermia is very small, even though a fan is used when sleeping at night. Because the fan can't drastically cool the air temperature in the room.

The notion regarding the dangers of sleeping with a fan has not been scientifically proven and still requires further research.

However, the use of fans does need to be considered, especially in terms of cleanliness. The fan must be cleaned to prevent the fan from spreading dust and dirt that can cause asthma and allergy symptoms to recur.

If you experience asthma or allergies due to using a fan while sleeping, consult your doctor for appropriate treatment.
